Title: Olefin recovery from gases by condensation - with heat recovery from demethaniser overhead using Ranque effect
Inventor: SCHIROKOV VASILIJ IVANOVITSCH
IPC: F25B9/04
Filed: 1979-07-30
Abstract: Recovery of olefins from feed gases contg. H2, CH4 and olefins is carried out by first cooling the feed gas in stages to recover an olefin-rich condensate, and passing the condensate to a demethaniser to separate an H2- and CH4-rich overhead stream (I) from an olefin bottoms stream. Stream (I) is then cooled and sepd. into a condensate stream (II) and a gas stream (III), and (II) is recycled to the demethaniser as reflux. Stream (III) is expanded utilising the Ranque effect to produce a relatively cold gas stream (IV) and a relatively warm gas stream (V). Stream (IV) is used to cool (I) and is then recombined with (V). The recombined gas in then expanded utilising the Ranque effect to produce a relatively cold gas stream (VI) and a relatively warm gas stream (VII). Stream (VII) is used to cool the feed gas by countercurrent heat exchange, and (VI) is used likewise after countercurrent heat exchange with (I). The process can be used to recover an ethylene- and propylene-rich prod. from debutanised prod. gases from the steam-cracking of naphtha. The process gives high olefin recoveries (99% or more) without the need for external cooling.

Patent DE-2942998-A1 (DE)
Inventor: ISHIKAWA SAKOU
IPC: G06F11/10
Filed: 1979-10-24
Abstract: In a system which employs SEC-DED codes constituted by data bits added to redundant bits and is capable of detecting and correcting a single bit error while detecting a double or more bit error, detection is made on miscorrection ascribable to a triple bit error. When a single bit error is detected by an error detecting and correcting circuit in the SEC-DED code read out from a memory, all the corrected data bits are inverted in state and rewritten in the memory after having been added to new redundant bits. Subsequently, the data bits together with the redundant bits are read out from the memory and supplied to the error detecting and correcting circuit. The data bits obtained from the error detecting and correcting circuit are compared with the corrected and inverted data bits available before being written in the memory, to thereby determine the presence of an error encompassing more than (m+1) bits on the basis of the result of comparison.
